SPINNING AND TWISTING MACHINE.

Specification of Letters Patent.

Patented April 14, 1908.

To all whom it may concern:

Be it known that we, THOMAS D. SINGLE- TON and WILLIAM GLEAsoN, citizens of the United States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spinning and Twisting Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in devices for facilitating the spinning and twisting of yarn and has for its object to provide a device'of simple and practical construction that is adapted to be rotated at a very high velocity, said device'being provided with an aperture through it for receiving the yarn, and also has means for engaging and twisting the yarn as it passes therethrough while rotating.

The device is also adapted to increase the capacity and efiiciency of the ordinary spinning and twisting frame as it may be rotated at a much higher velocity and thereby twists the yarn much faster than is possible with the old method. Then again, the cost of constructing a spinning or twisting frame is much reduced as the spindles, rings and many other parts, may be done away with by the use of our device. Again, ballooning of the yarn is prevented, which has heretofore been a great detriment to spinning, thus greatly diminishing the possibility of breaking down the thread, at the same time making it possible to lay the-fibers close and hard forming a stronger thread, and as a consequence doing away in a great measure with the necessity for singeing or shearing the fabric after being woven, as is the case where cloth is woven from yarns spun and twisted in the usual way. Then again, this simple device may be attached to any frame now in use and at a very small expense.

Another and very important advantage in the use of our device is that it may be run single in a drawing and spinning machine or it may be run double, that is after two or more yarns have been spun they may be con ducted to a third device in the same machine and there all be twisted together, thus doing away with the expense of the second operation which is that of twisting the yarn in another machine after it has been spun in the first machine.

The invention consists of other novel features and parts and combinations of the ,2 is its top board.

same as will be fully described hereinafter and then pointed out in the appended claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 illustrates one of our improved twisting devices attached to a spinning frame, the view being a diagram in section showing parts of the frame and the relative position of the new device to the usual parts looking in the direction of one end of the frame. Fig. 2 shows an arrangement of twisting devices in which two or more threads after being twisted separate in its individual twister are conducted to a third device where said threads are twisted together all in the same machine before being spooled. Fig. 8 is a front view showing three devices in operation and the arrangement of the belt for driving the same. Fig. 4-is a detail showing an enlarged view in section of one form of this twisting device held in its supporting bearing. Fig 5. is a top view showing one end of the device to better illustrate the offset pin around which the thread is passed. Fig. 6- shows an end View of the device. Fig. 7 is a modification showing the end of the tubular body portion cut down forming an outer head.

Referring to the drawings, at 1 is the end frame of a spinning or twisting machine and The ordinary spools 3 and 4 carrying the yarn are mounted in the usual way on the stand 5 on said frame.

One form of the twisting device in question is herein illustrated as being a short tubular shaft 6, the hole through the same being comparatively small.

The device is adapted to be mounted in suitable bearings 77 in a bracket 8,which bracket may be supported in any convenient way, but is shown as resting on the top board 2. A pulley or whirl as at 9, or other arrangement for receiving the driving belt, may be formed on the tube. In this particular case illustrated the whirl is formed by providing flanges or collars 1010 on either side to hold the belt in position while run ning over the tube. The said tube is provided with an outer head at one end which may consist of a thin circular plate 11 having a small hole 12 through it at its center portion through which the thread is passed. This plate 1s removed a short distance from the end of the tube and supported on pins 1313 which extend outward from the end of said tube. The edge of the tubular member 6 is scored or recessed at 14 for the purpose of allowing the thread to be passed around the end of the inwardly projecting pin 15. This pin 15 is set parallel with the axis of the tube and is ofiset from the center and rigidly supported from the plate or outer head 11, its inner end extending back beyond the end of the tubular member into the recessed portion whereby after the thread has been passed around this end it is practically locked thereon and cannot be inadvertently removed. The arrangement of this pin,

whereby the thread may be so readily passed 1 around or over the end of the same and also looked against accidental removal therefrom, is an essential feature of our invention, and by its use the twisting device may be very easily threaded up without the possibility of the thread jumping off of the pin. The rear end of this tube may be a duplicate of the front end if desired, and be provided with a plate 17 having an offset pin 18 around which the thread may also be passed. This construction has a double advantage, one being to balance the pin at the opposite end, and then again, the thread may be passed around this second pin when it is desired to increase the tension on the same.

The device is preferably driven by an ordinary driving band or belt 19 which passes around the tube between the collars and thence down around the idler pulleys 20 and back around the usual driving drum 21 mounted in the frame.

Another and important feature of this device is the simplified construction illustrated in Fig. 7 wherein the tubular portion 6 is shown at being cut down or recessed as at 30, forming an outer head 31 with a space be tween it and the end of the tubular portion proper, the stock 32 at the lower side being used in place of the pins 1313 to support said head at a distance from the end of said tube.

In the operation of our improved twisting device, when applied to an ordinary drawing or spinning frame, the thread 16 is led from the usual bobbins 3 and 4 through the drawing or feeding rolls 22-22, thence it is drawn through the tube by means of a hook and passed around either one or both of the offset pins at the ends of the tube whereby the thread receives the necessary twist as the device is rapidly rotated. From here the thread is led to the spool 23 on which it is wound, said spool being driven by means of the contact wheel 24, which wheel is rotated in time with the said roll 22 through the belt 25.

An essential feature in the use of our device is that twisting may also be combined with spinning on the same frame which is accomplished as follows: Instead of leading the thread through a single twisting device and direct to the spool, as illustrated in Fig. 1, two or more threads are conducted over suitable guides 26 and 27 to a single and independent twisting tube 28 whereby these several yarns are combined and twisted together into one thread and from this last twister are conducted to and wound onto the spool 29 in the manner best illustrated in Fig. 2.

Our improved twisting device is extremely simple and inexpensive in construction, effective in its, operation, reduces the cost of production, and improves the quality of the yarn.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is:

In a spinning and twisting machine, a twister head comprising a short tubular body portion, a plate or outer head supported on said body a short distance therefrom providing a space between them, a pin at one side of the center set substantially parallel with the axis of said body portion and adapted to extend across said space, said pin having one free end over which the bite of said thread is adapted to be passed.

In testimony whereof we afiix our signa tures in presence of two witnesses.
